| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening U-bolt nuts. | Tighten nuts to the recommended torque specification for the chosen mounting hardware to prevent pipe deformation or damage to the bolt threads. |
| Using the wrong size U-bolt for the pipe. | Verify that the U-bolt's inside width and length are appropriate for the specific nominal pipe size to ensure a secure and proper fit. |
